Y=9(x−2)²<span>−5 is the solution
</span>
Explanation in full below

Using the vertex co-ordinates we can deduct the formula
y=a(x-2)²-5 

using the co-ordinate (3,4), use x=3, y=4 to find a

y=a(x-2)²-5 
4=a(3-2)² -5
4=a(1)²-5
4=a-5
a=9

Subsituting a into the first equation
y=a(x-2)²-5 
y=9(x-2)²-5 

The solution is y=9(x-2)²-5

Solve for b. -11b+7 = 40−11b+7=40
Oksana_A [137]

Answer:

This equation is false

Step-by-step explanation:

Well,

-11b + 7 = 4 - 11b + 7 = 40

combine like terms

-11b + 7 = -11b + 3 = 40

Communicative property

-3 to both sides

-11b + 4 = -11b = 40

-4 to both sides

-11b = -11b = 36

+11b to both sides

0 = 36

0 is not equal to 36 meaning that this equation is false.

<em>Thus,</em>

<em>the equation given is false.</em>

<em>Hope this helps :)</em>
